Hi guys, is there a way to patch all vanilla guns quickly, other than going through each item in the folder to add in support for Guns n Ammo mod resource?
Nope. You're gonna have to patch all the vanilla guns yourself. The easiest would be to start with the procedural weapons first as it's all just a single file that generates a random weapon out of 3 different types of sprites (Front, Mid, Back). With unique weaponry such as the adaptable crossbow or a Novakid crafted gun, yeah you're gonna have to patch each and every one of them. Good luck.
